2 Claims. (Cl. 20S-46) In my Patent No. 1,282,167, Oct. 22, 1918, I have described wrapping articles with a strip of craped paper helically applied under tension and by virtue of the craping differentially expansible Fig. 3 is an enlarged fragmentary section taken circumferentially of the outer periphery of the wrapped article; and

Fig. 4 is a fragmentary plan view of a modified 5 and resilient. By the latter word I4 mean thatV form of wrapping strip. 5 the crapings which were partially stretched out In all these figures it will be understood that either in the application of the wrapping or in the disclosure is diagrammatic, .particularly as response to shocks to which the wrapped article regards the proportion of the parts, and that the is submitted in use tended to regain their original showing of the crapings, particularly in Figs. 1

The row wrapping strip 'l wound thereabout in a 15 l" resiliency of craped paper, however, is limited in series of overlapping, helical turns or spires.

'I'he 55 most substantial bodyof rubber is thus disposed` leased, it will snap back immediately approximately toits originally craped form, the speed and extent of the reaction being comparable to that of an ordinary rubber band. In fact when the strip is coated on one side, the reaction is such that if so stretched out and released the strip will roll up on itself with the coated side inward.l

In some instances to effect an economy oi"y rub- -ber I may utilize a strip as shown in Fig. 4 comprising the craped paper base 9 to which the rubber coating Ila is applied in the form of longitudinally extending, relatively narrow strips.

In the wrapping described the very large differential expansion of the craped paper s is preserved, permitting a ready fitting of the wrapping to the article, notably in the case of annular articles, while the greatly increased resiliency y binds the article very closely and takes up the ping. The adjacent turns of the wrapping are shocks of handling without danger of breakage. Notably -when the rubber coating is complete, the wrapping is water-resisting as a whole and there is no danger of the grip of the wrapping relaxing f under dampness.

A rubberized coating of the kind described has a substantial frictional grip. While I prefer for reasons of economy to coat but one side of the sin'ip, I may, as best indicated in Fig. 3, fold over one edge of the strip 1 so that the coated edge of this folded over portion will contact with the coated edge of the underying spire cf the wrapthen held firmly together and will not become clisplaced in use so as to expose the article.

'The frictionalgrip vof'the tire Wrapped as herein described on another tire similarly wrapped or on a supporting surface will permit such uniform piling of the tires without objectionable movement of one relative to another with a corresponding saving of space.
